This 1929 Hudson Dual Cowl Phaeton convertible will be one of the featured convertibles on display for the 12th Annual Antiques on the Bay show in St. Ignace Saturday, June 21, from 9 a.m. to 4 p.m. Admission to the show is free of charge. The display will follow an antique car procession over the Mackinac Bridge from Mackinaw City to St. Ignace Friday at 4:30 p.m. (Photograph courtesy of Nostalgia Productions) In 1956, a young motorhead named Ed Reavie pulled up to LaSalle High School in his first car, a red, 1953 Ford Sunliner convertible, a vehicle, he recalls, that stood right "at the top of the food chain" in the automobile world.

"I felt like a pretty cool kid in high school driving that, let me tell you," he said.

Convertibles have always been prized highly by car enthusiasts, so this weekend, as organizer of the 12th Annual Antiques on the Bay show in St. Ignace, Mr. Reavie chose to feature them.

As many as 60 are expected to be displayed at the St. Ignace Marina, where they will be admired along with all manner of cars and trucks 1983 and older, against the blue backdrop of Moran Bay and the boats in the harbor.

"It's the perfect setting for an antiques show," Mr. Reavie said.

Antique car owner J.R. Hostetler agreed. As maintenance manager of Hostetler's Hudson Auto Museum in Indiana, he knows a lot about cars and the quality of car shows. In fact, St. Ignace will be the first place he and his father, Eldon, will show cars this year, he said.

A heavyweight in the competition for Best of Show, their yellow and-cream 1929 Hudson Dual Cowl Phaeton convertible will be hard to beat.

"That car is magnificent," Mr. Reavie said.

In its time, the Hudson was as close to a chauffeured limousine as its wealthy owners could obtain, Mr. Hostetler explained.

"It is almost like two cars," he said. Among several opulent features, it has a windshield for both the front and back seats, allowing for a warmer ride than other convertibles of its time. The back seats can also be covered, transforming it into a two-seater.

"The look and style of the '20s cars is so classic," Mr. Hostetler said.

The Hostetlers have been in the antique car business for years. Eldon Hostetler collected most of the cars in the Hostetler museum, and to ensure that they remained together, he donated them all to the town of Shipshewana, Indiana, which built the facility to house them. They range from 1909 to 1956 models.

Mr. Hostetler maintains the right to show his cars, and St. Ignace showgoers will benefit, free of charge, at the Antiques on the Bay show Friday, June 20, and Saturday, June 21.

The first of Nostalgia Production's 2008 events, the show averages about 120 antique car entries a year.

This is a show for automobile purists, Mr. Reavie said. Each vehicle must appear as it did when it rolled off the assembly line, and six expert judges will ensure their authenticity.

For participants, registration is Friday from 9 a.m. to 5 p.m. at the St. Ignace Chamber of Commerce. A second registration period is Saturday, from 8 a.m. until noon, at the Brewbaker trailer at the St. Ignace Marina.

To begin the weekend, drivers will converge for the annual Mackinac Bridge Rally at 4:30 p.m. Friday at the Welcome Center in Mackinaw City. They will cross the bridge, proceed to Best Western Harbour Point in St. Ignace, arriving about 5:15 p.m., and then take a turn past the Long Term Care facility at Mackinac Straits Hospital, where residents will be outside waiting to see the old cars.

They really like the procession, Mr. Reavie said. "Many remember those cars. It really jogs memories."

The cars will be displayed and judged at the marina Saturday from 9 a.m. to 4 p.m. An awards ceremony will follow at St. Ignace Middle School from 6 p.m. to 8 p.m. Hagerty Insurance and Nostalgia Productions will give out several awards. Among them will be Best Convertible and Best of Show. Winner of the latter will receive a two-night stay at Grand Hotel on Mackinac Island.
